This invention, which relates to a container in the form of a barrel,comprises a plywood drum equipped with metallic heads, the upper ofwhich is provided with a removable closure. The

` present improvements are directed to such a container -of compositioncharacter wherein the entire structure can be made so tight andconvenient for use as to be well adapted for the recep- I tion' ofvarious viscous or semi-solid substances set forth in the accompanyingdrawing wherein- Figure 1 is a'view in perspective of the container withthe closure iltted in place;

Figs. 2` and 3 are detailsin section, on an enlarged scale, taken onlines 2-2 and 3 3, respectively, of Fig. 1;

Figs. 4 and 5 are perspective views of the container top and bottom,respectively; I

Fig. 6,- which is a view generally similar to Fig. 2 shows a modiiiedconstruction adjacent the upper head of the drum; and

Fig. 7 is a 'similar view showing afurther modified construction,

As shown, the container comprises a body-in the form of a cylindricalplywood drum D. `The plies comprising the barrel are desirably unitedover every portion of their contacting surfaces by a suitable adhesive.edges of the drum may be covered over with a strip 6 which extendsdesirablyfor the length of the drum to which itmay be convenientlysecured as by means of staples The cylindrical plywood drum is desirablycoated interiorly as at 8 with latex or other sealing material whichwill be resistant to attack'by lof the container. Such a coating isdesirably extended around the meet-v ing edgesof the drum where thejoint occurs, as well as over the opposite ends of the drum and upon theexterior surface thereof for a limited distance from each end whereplywood hoops H are fitted in place. The outer circular edge of eachhoop is desirably arranged flush with the proximate end of the drum (seeFigs. 2 and 3), and the ends of the hoops may be chamfered andoverlapped'in the usual way (see Fig. l). A

In general, the construction ofthe drum and the reinforcing hoopsapplied exteriorly thereof The joint at the meeting'- 2 Claims. (Cl.217-.-76)

may be as described up to this point. The metallic -parts of the presentcontainer are conn'ed mostly to the two-heads, one being the bottom Band the other the top T. Except for the provision' of a removableclosure which is iltted to the top, these two alike. l

Referring now to Fig. 3, the bottom B comprises by preference a head inthe form of a iiat sheet metal plate I I) with a depending circular wallII adapted for close fitting within the drum adjacent its lower end,this wall then executing a return bend I2 which underlies the proximateend of the drum to provide a collar I3 whichy is extended upwardlywithin the hoop. H to terminate, if desired, at a point which is aboutopposite the plate I0. The coating 8 which is applied to the inner andouter surfaces-of the drum, as

already explained, lies to the inside of the circular wall II and collarI3, as shown, The assembly of the metallic bottom with the plywood visextended around the .drum to which is also tted the two hoops H may be'completed by a plurality of staples I4 whose parallel shanks traversethe hoop andv drum also the spaced collar and circular wall of thebottom with the pointed endsof the staples clinched against this wall.Such an assembly makes for a tight construction and, with the aid of anappropriate coating as container is admirably suited for the retentionof grease or other semi-solid or viscous substances. The container topT, which is generally similar to the .bottom just described, comprises ahead in the form of a sheet metal top'plate 20 with anl upstandingcircular wall 2| which at 22 executes a reverse bend to provide a collar23,- the circular wall and collar being adapted to extend alongside ofopposite surfaces of the drum adiacent the upper end thereofwith thecoating 8 interposed therebetween to maintain a leakproof connection.The upper hoop H which is fitted around the drum adjacent its upper endcollar and therebelow. As by means of staples 24 which traverse thehoop, drum, the collar and circular wall of the head, these severalparts are interconnected xedly, the staple ends being clinched bypreference against the circular wall as.shown.:- y

The top plate 20 is in the form of an annulus with a center openingadjacent which is a slight upward hump 25 forming part of a bend from4which dependsfafiange 26 dening the central opening of the head. `Anumber'of socket memparts may be substantiallyl already described, the

vide, when outwardly peaned as at 3|, a simplelocking means whereby eachof these members is xedly secured in place.

The closure C, also of sheet metal, comprises a fiat plate with anupturned marginal ange depending from the head` 36 adapted to lie to theinside of the fiange 26,

the closure being also formed with a ledge 31 which is extendedoutwardly from the flange 36. This ledge is desirably formed with itsouter edge rolled downwardly and inwardly in the form of a bead 38adapted, when rested upon the head, to maintain the ledge in slightlyspaced relation thereto. Openings are provided in the ledge, one inregister with each socket member, for the reception of the bolts 28whose heads 29 are adapted to bear against the ledge when the bolts arescrewed home to secure the closure tightly in place. A gasket 39 adaptedto be tted around and over the hump 25 serves to complete a leak-proofconnection between the closure and the top head.

In Fig. 6 I have illustrated a plywood drum D to whose upper end is.applied a head comprising a at sheet metal plate 20 with an upstandingcircular wall 2i which at 22 executes a reverse bend to provide a collar23. The circular wall and collar are adapted to extend alongside ofopposite surfaces upper end with an ably of fabric impregnated with aresistant or repellant material suitable to withstand the intendedcontents of the drum. In this construction the collar 23 extends downover the outside of the drum only a short distance so as to terminatejust above the circular row of staples 2d which interconnect the hoop,drum and inside wall of the head. The lining 40 is desirably extendeddownwardly to and over the opposite end of the drum where a duplicatehead may be provided, all as hereinbefore described in connection withFigs. 2 and 3. The showing in Fig. 7 is generally similar except ythatthe collar 23 is extended further downwardly to terminate about oppositethe lowerend of the hoop H, and in lieu of the applied lining of fabricor other material I have here indicated a coating 4|as of latex whichmay be conveniently sprayed on the interior surface of the drum and ofits two heads.

The container of this invention combines the advantages of plywood forthe cylindrical body and of sheet metal for the two heads, one of of thedrum adjacent its interposed lining 40, desirwhich is tted with ametallic removable elosure. Each of the heads is extended to providespaced circular walls between which is received the proximate end of theplywood drum. Thespaced metallic walls are joined by a rounded edgeforming an end rim for the container. No matter which way the drum bestoodit is the rounded metal edge that is rested against the supportingfloor. The plywood drum is thus protected and reinforced at its two endsby the metal of the associated heads. y

While the two hoops applied exteriorly of the plywood drum serve as areinforcement therefor, there is still lacking any means for assuring`perfect circularity of the drum. A tendency toward slightnon-circularity results from the joint which is always present at themeeting ends of f when the drum is This is of advantage in that the drumis enabled to better withstand compressive forces and to resistdisruption or breakage due to excessive rigors in handling. In addition,the rounded metal rims whereon the ends of the drum are supportedl willprovide a better rolling surface,

thus moved about in accordance wlth usual practice.

The closure which is fitted to the top head is permitted to make a tightseal therewith by reason of the compressible gasket which is interposedbetween the facing surfaces of the closure and head. It is not necessarythat the .closure be tted tightly to the head, only that means beprovided for drawing the closure into tight engagement with 'the gasketthat is interposed between itself and the head. This I have accomplishedin a simple manner by the provision of threaded socket members with eachof which may engage a bolt whose head is adapted to bear with pressureagainst the upper side of the ledge which is extended outwardly from theclosure. In such a construction the closure may be secured tightly afterthe container is filled, removal of the closure being accomplished bythe smple operation of loosening the bolts after which further usethereof is usually not called for. i
